I am training yolov7 on my custom data annotated on roboflow in google colab. This is the tutorial that i am following: [Google Colab](https://colab.research.google.com/github/roboflow-ai/notebooks/blob/main/notebooks/train-yolov7-object-detection-on-custom-data.ipynb#scrollTo=1iqOPKjr22mL)

Traceback (most recent call last):

AttributeError: module ‘numpy’ has no attribute ‘int’.  
`np.int` was a deprecated alias for the builtin `int`. To avoid this error in existing code, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.  
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:  
[NumPy 1.20.0 Release Notes — NumPy v2.1.dev0 Manual](https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations). Did you mean: ‘inf’?
